We show that the No-Scale Flipped SU(5) construction is transparently consistent with recent LHCb results for decays, due primarily to suppression from the rather small value of tanβ ∼ 20 that is globally enforced across the model space. This fact should be interpreted in conjunction with the demonstrated evasion of mass limits from the ATLAS and CMS SUSY searches and the more important potential explanation of small observed excesses in the multijet data. The No-Scale Flipped SU(5) benchmark model that best fits these excesses has a gaugino mass scale of M1/2 = 708 GeV, which drives masses for the bino-dominated LSP GeV, light stop GeV, gluino GeV, and heavy squark GeV. The corresponding total prediction for the rare B-decay of suggests that the SUSY contribution may indeed be much smaller than that expected from the Standard Model in this framework, fitting quite comfortably within the very tightly constrained region remaining viable after the most recent LHCb measurements.
